TO ALL WHOM IT MAY CONCERN:

Be it known that I, I. Mt THOMPSON, of Edinburg, in the county of Johnson, and State of Indiana, have invented a new and improved Water-Wheel; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings; forming part of this specification.

This invention relates to a new and improved water-wheel of that class which are fitted or placed on a vertical shaft and rotate in a horizontal plane.

The-invention consistslin combining two wheels inone, and providing each with a series of gates, arranged 4in such a manner that both sets of gates may be operated, opened, and closed simultaneously by a single manipulation on the part of the operator, all being constructed and arranged in such a-'manner that a large percentage of thc'tpower of the water is obtained. In the accompanying sheet of drawings- Figure I is a plan cr top view of my invent-ion. l I

.Figure 3, a detached perspective view of the wheel:

Figure 4,*a plan or top view of the same.

Similar 'letters of reference indicate corresponding parts. t

A represents the wheel, which is fitted on a vertical shaft, B, and is composed of an angle-shaped rim, having a horizontal upper part, a, and a vertical lower part, o, as 'shown clearly in iig. 2. On the exterior of this rim, underneath the horizontal part, a, thereof', there is a series of buckets, c, the shape of which is shown clearly iii iig. 3, the lower parts being slightly inclined from a horizontal plane, and the upper parts'extending.. downward from a, and having a rather quick curve to form a connection with the lower parts. Withintherim ofthe wheel there isa series of radial buckets, d, inclined in their transverse section, and extending from the rim to the hub e 'of the wheel, the buckets d being inclined in the same direction as thebu'clrets c.

The wheel thusconstructed is fitted within an annular frame, O, composed 'of an upper and lower rim, e e', conne'otedby standardsf, the space between the rims 'being enclosed by gates g g', the gates g being hung on pivot-bolts h, and the gates g being xedor immovable. The bolts z. pass up through the top rim e, and have bent levers, D, fitted on them, the bolts passing through the levers at their angles. These levers extendinward and towards the centre of the wheel, and are all connected to a collar, E, on shaft '13, by pins z', which pass through oblong slots 7' in the levers. The lower end of' the collar E has a circular plate, F, attached, which is i tted and works in an annular rebate inthe inner edge ofthe upper rim, e, ofthe frame C, and the plate F has a series of radial openings, k, ma'de in it, which correspond with similar openings Zin e. The plate F, it will be seen, forms a gate for the buckets d, and this gate has a segment-toothed plate, m, attached to it, into which a pinion, n, gears, said pinion being fitted on a suitable shaft. By turning thc pinion n the gate f will be turned, `and the gates g also moved, both series of gates being opened or closed simultaneously, to admit water to the buckets c and or to shut it oit` therefrom, as may be desired. l

.By this construction and arrangement of parts a very efficient water-wheel is obtained, a large percentage of the power of the water being obtained.

Iclaim as new, and desire to secure-by Letters Patent- Y The combination of thc two setsof ,buckets c d with the two sets of gates g and F, all constructed and arranged to operate in'the manner substantially as and for the purpose set forth.
